![]() Characteristic eruptive activity consists of Strombolian eruptions from the lava lake or from one of several subsidiary vents, all within the volcano's inner crater. The summit contains a persistent convecting phonolitic lava lake, one of five long-lasting lava lakes on Earth. It is the current eruptive centre of the Erebus hotspot. Mount Erebus is the world's southernmost active volcano. Geology and volcanology Anorthoclase crystal (45 mm long) from Mt. The volcano was the site of the Air New Zealand Flight 901 accident, the Mount Erebus disaster, which occurred in November 1979. The volcano has been active since about 1.3 million years ago and has a long-lived lava lake in its inner summit crater that has been present since at least the early 1970s. With a summit elevation of 3,794 metres (12,448 ft), it is located in the Ross Dependency on Ross Island, which is also home to three inactive volcanoes: Mount Terror, Mount Bird, and Mount Terra Nova. It is the sixth-highest ultra mountain on the continent. Mount Erebus ( / ˈ ɛr ɪ b ə s/) is the second-highest volcano in Antarctica (after Mount Sidley), the highest active volcano in Antarctica, and the southernmost active volcano on Earth. ![]() Elevation: 3,794 m (12,448 ft) Prominence: 3,794 m (12,448 ft) Geology Type: Stratovolcano (composite cone).(claimed by New Zealand as part of the Ross Dependency) ![]() Scientific study of the volcano is also facilitated by their proximity to McMurdo Station (U.S.) and Scott Base (N.Z.), both sited on Ross Island approximately thirty-five kilometres away. The volcano is scientifically remarkable in that its relatively low-level and unusually persistent eruptive activity enables long-term volcanological study of a Strombolian eruptive system very close (hundreds of metres) to the active vents, a characteristic shared with only a few volcanos planetarily, such as Stromboli in Italy. Characteristic eruptive activity consists of Strombolian eruptions from the lava lake or from one of several subsidiary vents, all lying within the volcano\'s inner crater. ![]() Geology And Volcanology: Mount Erebus is currently the most active volcano in Antarctica and is the current eruptive zone of the Erebus hotspot. Blackmer, an iron-worker for many years at McMurdo Station and the South Pole, accomplished a solo ascent in approximately seventeen hours via snow mobile. Its first known solo ascent and the first winter ascent was accomplished by British mountaineer Roger Mear in March 1985, a member of Robert Swan\'s "In the Footsteps of Scott" expedition. Climbing: Mount Erebus was first climbed (to the rim) by members of Sir Ernest Shackleton\'s party in 1908. The volcano has been observed to be continuously active since 1972 and is the site of the Mount Erebus Volcano Observatory run by the New Mexico Institute of Mining and Technology. With a summit elevation of 3,794 metres (12,448 ft), it is located on Ross Island, which is also home to three inactive volcanoes, Mount Terror, Mount Bird, and Mount Terra Nova. It is the 6th highest ultra mountain on an island. Mount Erebus is the second highest volcano in Antarctica (after Mount Sidley) and the southernmost active volcano on earth.
